FMIPA UI Introduces Simple DNA Isolation to Junior High School Students to Enhance Science Literacy

The Department of Biology, Faculty of Mathematics and Natural Sciences, Universitas Indonesia (FMIPA UI), introduced a simple DNA isolation method to 31 students from SMPIT Raflesia during a community service activity themed “Introduction to Creative and Educational Science through Ecoprinting, Microorganism Diversity & Fermented Foods, and Plant DNA Extraction”, held on Saturday (October 11).

The activity, held at the Prof. Dr. Ir. Soemantri Brodjonegoro Auditorium and the Biology Laboratory of FMIPA UI, aimed to enhance science literacy among students, particularly in the field of molecular biology. Many middle school students have yet to grasp the concept of DNA concretely, as learning in schools is often still theoretical.

In fact, understanding DNA is important for students to grasp the fundamentals of life and modern biotechnology. By learning how DNA works, students can better understand concepts such as inheritance of traits, genetic health, and biotechnology applications in the fields of food and the environment.

The head of the community service team, Andi Salamah, Ph.D., explained that the isolation method used in this activity is cost-effective, simple to perform, and environmentally friendly. “This simple method allows students to understand the basic concepts of molecular biology without the need for expensive laboratory equipment,” she said.

She added, “This is part of our commitment to implementing the Three Pillars of Higher Education (Tridharma Perguruan Tinggi), particularly in community service through a creative and relevant approach.”

The event was opened by the Head of the Department of Biology, FMIPA UI, Prof. Anom Bowolaksono, Ph.D., who emphasized the importance of fostering an early interest in science. “Through activities like this, we instill a scientific foundation in a fun way so that the younger generation becomes accustomed to thinking critically and appreciating the scientific process,” he said.

The practical session was led by Fadhillah, Ph.D., who conducted an activity titled “Fun Science: Simple DNA Extraction to Foster Early Interest in Biology among SMPIT Raflesia Students.” The students were guided to extract DNA from fruits such as watermelon, pineapple, banana, papaya, and melon using common household materials like soap and shampoo containing Sodium Lauryl Sulfate (SLS) and non-SLS types, as well as simple tools available at home, such as spoons, glasses, tea strainers, and baby bottles with measurement markings as substitutes for measuring cups.

Students were asked to compare the extraction results using the two types of soap to observe the differences in the formed DNA precipitate. This activity encouraged students to think analytically and practice their scientific observation skills.

The activity involved a team of lecturers, students, and academic staff from the Department of Biology, FMIPA UI. The lecturer team consisted of Tety Maryenti, M.Sc., Ph.D.; Afiatry Putrika, S.Si., M.Si.; Niarsi Merry Hemelda, S.Si., M.Si., Ph.D.; and Dr. Retno Lestari, S.Si., M.Si.

The student team included Rafly Raditya Ardi, A. A. N. Aryasatyapradaputra, and Muhammad Dhiaulhaq, while the academic staff members involved were Asri Martini Wulani, S.Si.; Turino; Alexander Tianara, M.Sc.; Lutfiya Ammara Fahmidaria, S.Si.; and Taryana.

At the end of the activity, the students participated in an interactive Kahoot! quiz to test their understanding. Participants with the highest scores received prizes, and the event concluded with a group photo session.

Many participants admitted that they had just learned that DNA can be extracted and observed directly using simple household materials. Through this activity, FMIPA UI hopes to foster students’ curiosity and love for the world of science.
